Features

The WellZone™ 3W digital controller provides pressure control for single-phase 3-wire submersible well pump applications. It uses a 0-150 PSI pressure transducer to monitor the discharge pressure and turns the pump ON and OFF according to adjustable Start and Stop setpoints. The LCD allows for a quick view of the system pressure, run status, hours run and pump cycles. The rotary button provides the user with a simple navigation method through the menu and program settings. It features built in pump protection including rapid cycling and dry run. It is preprogrammed to run the pump as the pressure drops below 40 PSI and stop as the pressure rises above 60 PSI. High & Low-pressure settings are available with an auxiliary alarm relay.

Start Circuitry Overload Protector (For 2HP & 3HP only)

There is an additional overload (OL) protection device on 2HP and 3HP control panels. This OL device is for the protection of the START Circuitry and is located below the terminal blocks. Press the red button to reset.

• Q: What are the symptoms when the start overload is tripped?
  • A: There is a short in the start circuitry or a locked rotor situation. The pump will not start when this overload protector has tripped. Press the red button to reset. The digital display may also display “OVERLOAD” and must be reset (Press the ESC button for 4 sec).
• Q: How to check the circuit with a multimeter?
  • A: If the pump does not start after a reset. To verify that OL has reset, measure the resistance (ohm) from T1 and the black wires in the cap kit. It should measure continuity (<10 ohms). Check the start relay and capacitors as well.
• Q: How to reset?
  • A: To reset, wait at least 10 minutes after the trip to allow for the unit to cool down and press the red button.
• Q: What do you do if the start overload keeps tripping?
  • A: Check the capacitors and start the relay. Check the motor if locked. Check the ambient temperature in the control panel. The overload module will trip sooner if hot. Protect the control panel from direct sunlight.
